“…In the 1970s, research on thermal blooming mainly focused on adaptive optics [1][2][3][4][5][6][7] , high-power laser transmission [8][9][10] and other related fields. Based on the numerical simulation, the scaling laws of beam expansion [11] and phase compensation [12] have been investigated. In recent years, Ji and et al have theoretically studied the thermal blooming effect of laser beams propagating through the atmosphere [13,14] and seawater [15] .…”

When a high-power laser beam propagates in an absorbing medium, the thermal blooming effect cause the phase distortion of the beam, which will seriously affect the beam quality. In this paper, with the help of the laser propagation theory and thermo-optic coefficient experiment, the phase change of Gaussian beam propagating in various concentrations of ink-ethanol is investigated. The result shows that the phase change is proportional to the input power, which may provide the theoretical and experimental basis for phase compensation, and have potential applications in the adaptive optics, underwater optical communications, biological tissue imaging and other related field.

This paper carried out a study on the contribution of wind farm to power balance of power system by wind power output control. The study mainly focuses on active power control capability of double feed induction generator (DFIG) based wind turbine, active power control mode of wind farm and capability of wind farm to participating in peak-load regulation. According to the National standard of China GB/T 19963-2011, a study case is given to simulate the impact of wind farm grid integration based on a real power system in order to validate the active power mode and control process presented in the paper.
